"dtml-let" doesn't understand type annotations, so you are setting a
variable called 'x:int', which isn't what you want.  You need to do the
integer conversion in Python, like so:

<dtml-let x="_.int(REQUEST.get('prod_config')" ...>

See the DTML reference guide at zope.org for more useful methods of "_".
